An object at rest stays at rest; an object in motion stays in motion unless acted on by an unbalanced force.

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F=ma).

For every action, there is an equal and opposite reaction.

In a closed system, the total momentum remains constant.

In a closed system, the total energy remains constant.

Describes the behavior of matter and energy at the atomic and subatomic levels, involving probabilistic interpretations.

A fundamental limit to the precision of certain pairs of properties (e.g., position and momentum) known simultaneously.

If two systems are each in thermal equilibrium with a third, they are in thermal equilibrium with each other.

Energy cannot be created or destroyed, only transformed.

Total entropy of an isolated system can only increase or stay constant.

Entropy of a perfect crystal at absolute zero is zero.
